SEQUENCE LISTING

The present application is being filed along with a Sequence Listing in electronic format. The Sequence Listing is provided as a file entitled BIOL0240WOSEQ_ST25.pdf created Mar. 30, 2015, which is 320 Kb in size.

FIELD

Provided are compositions and methods for reducing expression of superoxide dismutase 1, soluble (SOD-1) mRNA and protein in an animal. Such methods are useful to treat, prevent, or ameliorate neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) by inhibiting expression of SOD-1 in an animal.

BACKGROUND

The soluble SOD-1 enzyme (also known as Cu/Zn superoxide dismutase) is one of the superoxide dismutases that provide defense against oxidative damage of biomolecules by catalyzing the dismutation of superoxide to hydrogen peroxide (H2O2) (Fridovich, Annu. Rev. Biochem., 1995, 64, 97-112). The superoxide anion (O2-) is a potentially harmful cellular by-product produced primarily by errors of oxidative phosphorylation in mitochondria (Turrens, J. Physiol. 2003, 552, 335-344)

Mutations in the SOD-1 gene are associated with a dominantly-inherited form of amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease) a disorder characterized by a selective degeneration of upper and lower motor neurons (Rowland, N. Engl. J. Med. 2001, 344, 1688-1700). There is a tight genetic linkage between familial ALS and missense mutations in the SOD1 gene (Rosen, Nature, 1993, 362, 59-62). The toxicity of mutant SOD1 is believed to arise from an initial misfolding (gain of function) reducing nuclear protection from the active enzyme (loss of function in the nuclei), a process that may be involved in ALS pathogenesis (Sau, Hum. Mol. Genet. 2007, 16, 1604-1618).

ALS is a devastating progressive neurodegenerative disease affecting as many as 30,000 Americans at any given time. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.

Currently lacking are acceptable options for treating such neurodegenerative diseases. It is therefore an object herein to provide methods for the treatment of such diseases.

SUMMARY

Provided herein are methods, compounds, and compositions for modulating expression of superoxide dismutase 1, soluble (SOD-1) mRNA and protein. In certain embodiments, compounds useful for modulating expression of SOD-1 mRNA and protein are antisense compounds. In certain embodiments, the antisense compounds are modified oligonucleotides.

In certain embodiments, modulation can occur in a cell or tissue. In certain embodiments, the cell or tissue is in an animal. In certain embodiments, the animal is a human. In certain embodiments, SOD-1 mRNA levels are reduced. In certain embodiments, SOD-1 protein levels are reduced. Such reduction can occur in a time-dependent manner or in a dose-dependent manner.

In certain embodiments, such SOD-1 related diseases, disorders, and conditions are neurodegenerative diseases. In certain embodiments, such neurodegenerative diseases, disorders, and conditions include amyotrophic lateral sclerosis (ALS).

Such diseases, disorders, and conditions can have one or more risk factors, causes, or outcomes in common. Certain risk factors and causes for development of ALS include growing older, having a personal or family history, or genetic predisposition. However, the majority of ALS cases are sporadic and no known risk factors are known. Certain symptoms and outcomes associated with development of ALS include but are not limited to: fasciculations, cramps, tight and stiff muscles (spasticity), muscle weakness affecting an arm or a leg, slurred and nasal speech, difficulty walking, difficulty chewing or swallowing (dysphagia), difficulty speaking or forming words (dysarthria), weakness or atrophy, spasticity, exaggerated reflexes (hyperreflexia), and presence of Babinski's sign. As ALS progresses, symptoms and outcomes by include weakening of other limbs, perhaps accompanied by twitching, muscle cramping, and exaggerated, faster reflexes; problems with chewing, swallowing, and breathing; drooling may occur; eventual paralysis; and death.

In certain embodiments, methods of treatment include administering an SOD-1 antisense compound to an individual in need thereof. In certain embodiments, methods of treatment include administering an SOD-1 modified oligonucleotide to an individual in need thereof.

In certain embodiments, the antisense compound targeted to a SOD-1 nucleic acid is 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 80 linked subunits in length, or a range defined by any two of the above values. In certain embodiments the antisense compound is a modified oligonucleotide, and the linked subunits are nucleosides.

In certain embodiments, oligonucleotides targeted to a SOD-1 nucleic acid may be shortened or truncated. For example, a single subunit may be deleted from the 5′ end (5′ truncation), or alternatively from the 3′ end (3′ truncation). A shortened or truncated antisense compound targeted to a SOD-1 nucleic acid may have two subunits deleted from the 5′ end, or alternatively may have two subunits deleted from the 3′ end, of the antisense compound. Alternatively, the deleted nucleosides may be dispersed throughout the antisense compound, for example, in an antisense compound having one nucleoside deleted from the 5′ end and one nucleoside deleted from the 3′ end.

When a single additional subunit is present in a lengthened antisense compound, the additional subunit may be located at the 5′ or 3′ end of the antisense compound. When two or more additional subunits are present, the added subunits may be adjacent to each other, for example, in an antisense compound having two subunits added to the 5′ end (5′ addition), or alternatively to the 3′ end (3′ addition), of the antisense compound. Alternatively, the added subunits may be dispersed throughout the antisense compound, for example, in an antisense compound having one subunit added to the 5′ end and one subunit added to the 3′ end.

It is possible to increase or decrease the length of an antisense compound, such as a modified oligonucleotide, and/or introduce mismatch bases without eliminating activity. For example, in Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992), a series of oligonucleotides 13-25 nucleobases in length were tested for their ability to induce cleavage of a target RNA in an oocyte injection model. Oligonucleotides 25 nucleobases in length with 8 or 11 mismatch bases near the ends of the oligonucleotides were able to direct specific cleavage of the target mRNA, albeit to a lesser extent than oligonucleotides that contained no mismatches. Similarly, target specific cleavage was achieved using 13 nucleobase oligonucleotides, including those with 1 or 3 mismatches.

Gautschi et al (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated the ability of an oligonucleotide having 100% complementarity to the bcl-2 mRNA and having 3 mismatches to the bcl-xL mRNA to reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide demonstrated potent anti-tumor activity in vivo.

Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358,1988) tested a series of tandem 14 nucleobase oligonucleotides, and a 28 and 42 nucleobase oligonucleotides comprised of the sequence of two or three of the tandem oligonucleotides, respectively, for their ability to arrest translation of human DHFR in a rabbit reticulocyte assay. Each of the three 14 nucleobase oligonucleotides alone was able to inhibit translation, albeit at a more modest level than the 28 or 42 nucleobase oligonucleotides.

Antisense Compound Motifs

In certain embodiments, antisense compounds targeted to a SOD-1 nucleic acid have chemically modified subunits arranged in patterns, or motifs, to confer to the antisense compounds properties such as enhanced inhibitory activity, increased binding affinity for a target nucleic acid, or resistance to degradation by in vivo nucleases.

Chimeric antisense compounds typically contain at least one region modified so as to confer increased resistance to nuclease degradation, increased cellular uptake, increased binding affinity for the target nucleic acid, and/or increased inhibitory activity. A second region of a chimeric antisense compound may optionally serve as a substrate for the cellular endonuclease RNase H, which cleaves the RNA strand of an RNA:DNA duplex.

Antisense compounds having a gapmer motif are considered chimeric antisense compounds. In a gapmer an internal region having a plurality of nucleotides that supports RNaseH cleavage is positioned between external regions having a plurality of nucleotides that are chemically distinct from the nucleosides of the internal region. In the case of an oligonucleotide having a gapmer motif, the gap segment generally serves as the substrate for endonuclease cleavage, while the wing segments comprise modified nucleosides. In certain embodiments, the regions of a gapmer are differentiated by the types of sugar moieties comprising each distinct region. The types of sugar moieties that are used to differentiate the regions of a gapmer may in some embodiments include β-D-ribonucleosides, β-D-deoxyribonucleosides, 2′-modified nucleosides (such 2′-modified nucleosides may include 2′-MOE, and 2′-O—CH₃, among others), and bicyclic sugar modified nucleosides (such bicyclic sugar modified nucleosides may include those having a 4′-(CH₂)n-O-2′ bridge, where n=1 or n=2 and 4′-CH₂—O—CH₂-2′). In certain embodiments, wings may include several modified sugar moieties, including, for example 2′-MOE. In certain embodiments, wings may include several modified and unmodified sugar moieties. In certain embodiments, wings may include various combinations of 2′-MOE nucleosides and 2′-deoxynucleosides.

Each distinct region may comprise uniform sugar moieties, variant, or alternating sugar moieties. The wing-gap-wing motif is frequently described as “X-Y-Z”, where “X” represents the length of the 5′ wing, “Y” represents the length of the gap, and “Z” represents the length of the 3′ wing. “X” and “Z” may comprise uniform, variant, or alternating sugar moieties. In certain embodiments, “X” and “Y” may include one or more 2′-deoxynucleosides. “Y” may comprise 2′-deoxynucleosides. As used herein, a gapmer described as “X-Y-Z” has a configuration such that the gap is positioned immediately adjacent to each of the 5′ wing and the 3′ wing. Thus, no intervening nucleotides exist between the 5′ wing and gap, or the gap and the 3′ wing. Any of the antisense compounds described herein can have a gapmer motif. In certain embodiments, “X” and “Z” are the same; in other embodiments they are different.

In certain embodiments, gapmers provided herein include, for example 20-mers having a motif of 5-10-5.

In certain embodiments, gapmers provided herein include, for example 19-mers having a motif of 5-9-5.

In certain embodiments, gapmers provided herein include, for example 18-mers having a motif of 5-8-5.

In certain embodiments, gapmers provided herein include, for example 18-mers having a motif of 4-8-5.

In certain embodiments, gapmers provided herein include, for example 18-mers having a motif of 5-8-7.

In certain embodiments, gapmers provided herein include, for example 18-mers having a motif of 6-8-6.

In certain embodiments, gapmers provided herein include, for example 18-mers having a motif of 6-8-5.

In certain embodiments, the modified oligonucleotide contains at least one 2′-O-methoxyethyl modified nucleoside, at least one cEt modified nucleoside, and at least one 2′-deoxynucleoside. In certain embodiments, the modified oligonucleotide has a sugar chemistry motif of any of the following:

ekddddddddekekee kekeddddddddekek eeeedddddddddkkee eeeeddddddddekeke eeeeddddddddkekee eeeeddddddddkkeee eeeeeddddddddkkee eeeekddddddddkeee eeeekdddddddkeeee eeekddddddddkeeee eeekkdddddddkkeee eekkdddddddddkkee eekkddddddddeeeee eekkddddddddkkeee ekekddddddddeeeee ekekddddddddkekee kekeddddddddeeeee, wherein e = a 2′-O-methoxyethylribose modified sugar, k = a cEt modified sugar, d = a 2′-deoxyribose sugar,

Target Nucleic Acids, Target Regions and Nucleotide Sequences

Nucleotide sequences that encode SOD-1 include, without limitation, the following: GENBANK Accession No. NM_000454.4 (incorporated herein as SEQ ID NO: 1), GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000 (incorporated herein as SEQ ID NO: 2), and the complement of GENBANK Accession No. NW_001114168.1 truncated from nucleotides 2258000 to 2271000 (incorporated herein as SEQ ID NO: 3).

It is understood that the sequence set forth in each SEQ ID NO in the Examples contained herein is independent of any modification to a sugar moiety, an internucleoside linkage, or a nucleobase. As such, antisense compounds defined by a SEQ ID NO may comprise, independently, one or more modifications to a sugar moiety, an internucleoside linkage, or a nucleobase. Antisense compounds described by Isis Number (Isis No) indicate a combination of nucleobase sequence and motif.

In certain embodiments, a target region is a structurally defined region of the target nucleic acid. For example, a target region may encompass a 3′ UTR, a 5′ UTR, an exon, an intron, an exon/intron junction, a coding region, a translation initiation region, translation termination region, or other defined nucleic acid region. The structurally defined regions for SOD-1 can be obtained by accession number from sequence databases such as NCBI and such information is incorporated herein by reference. In certain embodiments, a target region may encompass the sequence from a 5′ target site of one target segment within the target region to a 3′ target site of another target segment within the same target region.

Targeting includes determination of at least one target segment to which an antisense compound hybridizes, such that a desired effect occurs. In certain embodiments, the desired effect is a reduction in mRNA target nucleic acid levels. In certain embodiments, the desired effect is reduction of levels of protein encoded by the target nucleic acid or a phenotypic change associated with the target nucleic acid.

A target region may contain one or more target segments. Multiple target segments within a target region may be overlapping. Alternatively, they may be non-overlapping. In certain embodiments, target segments within a target region are separated by no more than about 300 nucleotides. In certain emodiments, target segments within a target region are separated by a number of nucleotides that is, is about, is no more than, is no more than about, 250, 200, 150, 100, 90, 80, 70, 60, 50, 40, 30, 20, or 10 nucleotides on the target nucleic acid, or is a range defined by any two of the preceeding values. In certain embodiments, target segments within a target region are separated by no more than, or no more than about, 5 nucleotides on the target nucleic acid. In certain embodiments, target segments are contiguous. Contemplated are target regions defined by a range having a starting nucleic acid that is any of the 5′ target sites or 3′ target sites listed herein.

Suitable target segments may be found within a 5′ UTR, a coding region, a 3′ UTR, an intron, an exon, or an exon/intron junction. Target segments containing a start codon or a stop codon are also suitable target segments. A suitable target segment may specifcally exclude a certain structurally defined region such as the start codon or stop codon.

The determination of suitable target segments may include a comparison of the sequence of a target nucleic acid to other sequences throughout the genome. For example, the BLAST algorithm may be used to identify regions of similarity amongst different nucleic acids. This comparison can prevent the selection of antisense compound sequences that may hybridize in a non-specific manner to sequences other than a selected target nucleic acid (i.e., non-target or off-target sequences).

There may be variation in activity (e.g., as defined by percent reduction of target nucleic acid levels) of the antisense compounds within an active target region. In certain embodiments, reductions in SOD-1 mRNA levels are indicative of inhibition of SOD-1 expression. Reductions in levels of a SOD-1 protein are also indicative of inhibition of target mRNA expression. Phenotypic changes are indicative of inhibition of SOD-1 expression. Improvement in neurological function is indicative of inhibition of SOD-1 expression. Improved motor function is indicative of inhibition of SOD-1 expression.

Hybridization

In some embodiments, hybridization occurs between an antisense compound disclosed herein and a SOD-1 nucleic acid. The most common mechanism of hybridization involves hydrogen bonding (e.g., Watson-Crick, Hoogsteen or reversed Hoogsteen hydrogen bonding) between complementary nucleobases of the nucleic acid molecules.

Hybridization can occur under varying conditions. Stringent conditions are sequence-dependent and are determined by the nature and composition of the nucleic acid molecules to be hybridized.

Methods of determining whether a sequence is specifically hybridizable to a target nucleic acid are well known in the art. In certain embodiments, the antisense compounds provided herein are specifically hybridizable with a SOD-1 nucleic acid.

Complementarily

An antisense compound and a target nucleic acid are complementary to each other when a sufficient number of nucleobases of the antisense compound can hydrogen bond with the corresponding nucleobases of the target nucleic acid, such that a desired effect will occur (e.g., antisense inhibition of a target nucleic acid, such as a SOD-1 nucleic acid).

Non-complementary nucleobases between an antisense compound and a SOD-1 nucleic acid may be tolerated provided that the antisense compound remains able to specifically hybridize to a target nucleic acid. Moreover, an antisense compound may hybridize over one or more segments of a SOD-1 nucleic acid such that intervening or adjacent segments are not involved in the hybridization event (e.g., a loop structure, mismatch or hairpin structure).

In certain embodiments, the antisense compounds provided herein, or a specified portion thereof, are, or are at least, 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% complementary to a SOD-1 nucleic acid, a target region, target segment, or specified portion thereof. Percent complementarity of an antisense compound with a target nucleic acid can be determined using routine methods.

For example, an antisense compound in which 18 of 20 nucleobases of the antisense compound are complementary to a target region, and would therefore specifically hybridize, would represent 90 percent complementarity. In this example, the remaining noncomplementary nucleobases may be clustered or interspersed with complementary nucleobases and need not be contiguous to each other or to complementary nucleobases. As such, an antisense compound which is 18 nucleobases in length having 4 (four) noncomplementary nucleobases which are flanked by two regions of complete complementarity with the target nucleic acid would have 77.8% overall complementarity with the target nucleic acid and would thus fall within the scope of the present invention. Percent complementarity of an antisense compound with a region of a target nucleic acid can be determined routinely using BLAST programs (basic local alignment search tools) and PowerBLAST programs known in the art (Altschul et al., J. Mol. Biol., 1990, 215, 403 410; Zhang and Madden, Genome Res., 1997, 7, 649 656). Percent homology, sequence identity or complementarity, can be determined by, for example, the Gap program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, Madison Wis.), using default settings, which uses the algorithm of Smith and Waterman (Adv. Appl. Math., 1981, 2, 482 489).

In certain embodiments, the antisense compounds provided herein, or specified portions thereof, are fully complementary (i.e., 100% complementary) to a target nucleic acid, or specified portion thereof. For example, an antisense compound may be fully complementary to a SOD-1 nucleic acid, or a target region, or a target segment or target sequence thereof. As used herein, “fully complementary” means each nucleobase of an antisense compound is capable of precise base pairing with the corresponding nucleobases of a target nucleic acid. For example, a 20 nucleobase antisense compound is fully complementary to a target sequence that is 400 nucleobases long, so long as there is a corresponding 20 nucleobase portion of the target nucleic acid that is fully complementary to the antisense compound. Fully complementary can also be used in reference to a specified portion of the first and/or the second nucleic acid. For example, a 20 nucleobase portion of a 30 nucleobase antisense compound can be “fully complementary” to a target sequence that is 400 nucleobases long. The 20 nucleobase portion of the 30 nucleobase oligonucleotide is fully complementary to the target sequence if the target sequence has a corresponding 20 nucleobase portion wherein each nucleobase is complementary to the 20 nucleobase portion of the antisense compound. At the same time, the entire 30 nucleobase antisense compound may or may not be fully complementary to the target sequence, depending on whether the remaining 10 nucleobases of the antisense compound are also complementary to the target sequence.

The location of a non-complementary nucleobase may be at the 5′ end or 3′ end of the antisense compound. Alternatively, the non-complementary nucleobase or nucleobases may be at an internal position of the antisense compound. When two or more non-complementary nucleobases are present, they may be contiguous (i.e., linked) or non-contiguous. In one embodiment, a non-complementary nucleobase is located in the wing segment of a gapmer oligonucleotide.

In certain embodiments, antisense compounds that are, or are up to 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleobases in length comprise no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a SOD-1 nucleic acid, or specified portion thereof.

In certain embodiments, antisense compounds that are, or are up to 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleobases in length comprise no more than 6, no more than 5, no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a SOD-1 nucleic acid, or specified portion thereof.

The antisense compounds provided herein also include those which are complementary to a portion of a target nucleic acid. As used herein, “portion” refers to a defined number of contiguous (i.e. linked) nucleobases within a region or segment of a target nucleic acid. A “portion” can also refer to a defined number of contiguous nucleobases of an antisense compound. In certain embodiments, the antisense compounds, are complementary to at least an 8 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 9 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 10 nucleobase portion of a target segment. In certain embodiments, the antisense compounds, are complementary to at least an 11 nucleobase portion of a target segment. In certain embodiments, the antisense compounds, are complementary to at least a 12 nucleobase portion of a target segment. In certain embodiments, the antisense compounds, are complementary to at least a 13 nucleobase portion of a target segment. In certain embodiments, the antisense compounds, are complementary to at least a 14 nucleobase portion of a target segment. In certain embodiments, the antisense compounds, are complementary to at least a 15 nucleobase portion of a target segment. Also contemplated are antisense compounds that are complementary to at least a 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or more nucleobase portion of a target segment, or a range defined by any two of these values.

Identity

The antisense compounds provided herein may also have a defined percent identity to a particular nucleotide sequence, SEQ ID NO, or compound represented by a specific Isis number, or portion thereof. As used herein, an antisense compound is identical to the sequence disclosed herein if it has the same nucleobase pairing ability. For example, a RNA which contains uracil in place of thymidine in a disclosed DNA sequence would be considered identical to the DNA sequence since both uracil and thymidine pair with adenine. Shortened and lengthened versions of the antisense compounds described herein as well as compounds having non-identical bases relative to the antisense compounds provided herein also are contemplated. The non-identical bases may be adjacent to each other or dispersed throughout the antisense compound. Percent identity of an antisense compound is calculated according to the number of bases that have identical base pairing relative to the sequence to which it is being compared.

In certain embodiments, the antisense compounds, or portions thereof, are at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100% identical to one or more of the antisense compounds or SEQ ID NOs, or a portion thereof, disclosed herein.

In certain embodiments, a portion of the antisense compound is compared to an equal length portion of the target nucleic acid. In certain embodiments, an 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleobase portion is compared to an equal length portion of the target nucleic acid.

In certain embodiments, a portion of the oligonucleotide is compared to an equal length portion of the target nucleic acid. In certain embodiments, an 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleobase portion is compared to an equal length portion of the target nucleic acid.

Modifications

A nucleoside is a base-sugar combination. The nucleobase (also known as base) portion of the nucleoside is normally a heterocyclic base moiety. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to the 2′, 3′ or 5′ hydroxyl moiety of the sugar. Oligonucleotides are formed through the covalent linkage of adjacent nucleosides to one another, to form a linear polymeric oligonucleotide. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside linkages of the oligonucleotide.

Modifications to antisense compounds encompass substitutions or changes to internucleoside linkages, sugar moieties, or nucleobases. Modified antisense compounds are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target, increased stability in the presence of nucleases, or increased inhibitory activity.

Chemically modified nucleosides may also be employed to increase the binding affinity of a shortened or truncated oligonucleotide for its target nucleic acid. Consequently, comparable results can often be obtained with shorter antisense compounds that have such chemically modified nucleosides.

Modified Internucleoside Linkages

The naturally occuring internucleoside linkage of RNA and DNA is a 3′ to 5′ phosphodiester linkage. Antisense compounds having one or more modified, i.e. non-naturally occurring, internucleoside linkages are often selected over antisense compounds having naturally occurring internucleoside linkages because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for target nucleic acids, and increased stability in the presence of nucleases.

Oligonucleotides having modified internucleoside linkages include internucleoside linkages that retain a phosphorus atom as well as internucleoside linkages that do not have a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous-containing linkages are well known.

In certain embodiments, modified oligonucleotides targeted to a SOD-1 nucleic acid comprise one or more modified internucleoside linkages. In certain embodiments, the modified internucleoside linkages are interspersed throughout the antisense compound. In certain embodiments, the modified internucleoside linkages are phosphorothioate linkages. In certain embodiments, each internucleoside linkage of a modified oligonucleotide is a phosphorothioate internucleoside linkage.

In certain embodiments, the modified oligonucleotides targeted to a SOD-1 nucleic acid comprise one or more phosphodiester internucleoside linkages. In certain embodiments, modified oligonucleotides targeted to a SOD-1 nucleic acid comprise at least one phosphorothioate internucleoside linkage and at least one phosphodiester internucleoside linkage. In certain embodiments, the modified oligonucleotide has a mixed backbone motif of the following:

sossssssssoooss, sooossssssssoss, sooosssssssssoss, soosssssssssooss, sooossssssssooss, sooosssssssssooss, sooossssssssssooss, sooosssssssssssooos, soooossssssssssooss, sooosssssssssssooss, sososssssssssssosos, and sooossssssssssoooss, wherein s = a phosphorothioate internucleoside linkage, and o = a phosphodiester internucleoside linkage.

Modified Sugar Moieties

Antisense compounds of the invention can optionally contain one or more nucleosides wherein the sugar group has been modified. Such sugar modified nucleosides may impart enhanced nuclease stability, increased binding affinity, or some other beneficial biological property to the antisense compounds. In certain embodiments, nucleosides comprise chemically modified ribofuranose ring moieties. Examples of chemically modified ribofuranose rings include without limitation, addition of substitutent groups (including 5′ and 2′ substituent groups, bridging of non-geminal ring atoms to form bicyclic nucleic acids (BNA), replacement of the ribosyl ring oxygen atom with S, N(R), or C(R₁)(R₂) (R, R₁ and R₂ are each independently H, C₁-C₁₂ alkyl or a protecting group) and combinations thereof. Examples of chemically modified sugars include 2′-F-5′-methyl substituted nucleoside (see PCT International Application WO 2008/101157 Published on Aug. 21, 2008 for other disclosed 5′,2′-bis substituted nucleosides) or replacement of the ribosyl ring oxygen atom with S with further substitution at the 2′-position (see published U.S. Patent Application US2005-0130923, published on Jun. 16, 2005) or alternatively 5′-substitution of a BNA (see PCT International Application WO 2007/134181 Published on Nov. 22, 2007 wherein LNA is substituted with for example a 5′-methyl or a 5′-vinyl group).

Examples of nucleosides having modified sugar moieties include without limitation nucleosides comprising 5′-vinyl, 5′-methyl (R or S), 4′-S, 2′-F, 2′-OCH₃, 2′-OCH₂CH₃, 2′-OCH₂CH₂F and 2′-O(CH₂)₂OCH₃ substituent groups. The substituent at the 2′ position can also be selected from allyl, amino, azido, thio, O-allyl, O—C₁-C₁₀ alkyl, OCF₃, OCH₂F, O(CH₂)₂SCH₃, O(CH₂)₂—O—N(R_(m))(R_(n)), O—CH₂—C(═O)—N(R_(m))(R_(n)), and O—CH₂—C(═O)—N(R₁)—(CH₂)₂—N(R_(m))(R_(n)), where each R₁, R_(m) and R_(n) is, independently, H or substituted or unsubstituted C₁-C₁₀ alkyl.

As used herein, “bicyclic nucleosides” refer to modified nucleosides comprising a bicyclic sugar moiety. Examples of bicyclic nucleic acids (BNAs) include without limitation nucleosides comprising a bridge between the 4′ and the 2′ ribosyl ring atoms. In certain embodiments, antisense compounds provided herein include one or more BNA nucleosides wherein the bridge comprises one of the formulas: 4′-(CH₂)—O-2′ (LNA); 4′-(CH₂)—S-2′; 4′-(CH₂)₂—O-2′ (ENA); 4′-CH(CH₃)—O-2′ and 4′-CH(CH₂OCH₃)—O-2′ (and analogs thereof see U.S. Pat. No. 7,399,845, issued on Jul. 15, 2008); 4′-C(CH₃)(CH₃)—O-2′ (and analogs thereof see PCT/US2008/068922 published as WO/2009/006478, published Jan. 8, 2009); 4′-CH₂—N(OCH₃)-2′ (and analogs thereof see PCT/US2008/064591 published as WO/2008/150729, published Dec. 11, 2008); 4′-CH₂—O—N(CH₃)-2′ (see published U.S. Patent Application US2004-0171570, published Sep. 2, 2004); 4′-CH₂—N(R)—O-2′, wherein R is H, C₁-C₁₂ alkyl, or a protecting group (see U.S. Pat. No. 7,427,672, issued on Sep. 23, 2008); 4′-CH₂—C(H)(CH₃)-2′ (see Chattopadhyaya et al., J. Org. Chem., 2009, 74, 118-134); and 4′-CH₂—C(═CH₂)-2′ (and analogs thereof see PCT/US2008/066154 published as WO 2008/154401, published on Dec. 8, 2008).

Further bicyclic nucleosides have been reported in published literature (see for example: Srivastava et al., J. Am. Chem. Soc., 2007, 129(26) 8362-8379; Frieden et al., Nucleic Acids Research, 2003, 21, 6365-6372; Elayadi et al., Curr. Opinion Invens. Drugs, 2001, 2, 558-561; Braasch et al., Chem.

A pharmaceutically acceptable diluent includes phosphate-buffered saline (PBS). PBS is a diluent suitable for use in compositions to be delivered parenterally. Accordingly, in one embodiment, employed in the methods described herein is a pharmaceutical composition comprising an antisense compound targeted to a SOD-1 nucleic acid and a pharmaceutically acceptable diluent. In certain embodiments, the pharmaceutically acceptable diluent is PBS. In certain embodiments, the antisense compound is a modified oligonucleotide.

Pharmaceutical compositions comprising antisense compounds encompass any pharmaceutically acceptable salts, esters, or salts of such esters, or any other oligonucleotide which, upon administration to an animal, including a human, is capable of providing (directly or indirectly) the biologically active metabolite or residue thereof. Accordingly, for example, the disclosure is also drawn to pharmaceutically acceptable salts of antisense compounds, prodrugs, pharmaceutically acceptable salts of such prodrugs, and other bioequivalents. Suitable pharmaceutically acceptable salts include, but are not limited to, sodium and potassium salts.

A prodrug can include the incorporation of additional nucleosides at one or both ends of an antisense compound which are cleaved by endogenous nucleases within the body, to form the active antisense compound.

Conjugated Antisense Compounds

Antisense compounds may be covalently linked to one or more moieties or conjugates which enhance the activity, cellular distribution or cellular uptake of the resulting oligonucleotides. Typical conjugate groups include cholesterol moieties and lipid moieties. Additional conjugate groups include carbohydrates, phospholipids, biotin, phenazine, folate, phenanthridine, anthraquinone, acridine, fluoresceins, rhodamines, coumarins, and dyes.

Antisense compounds can also be modified to have one or more stabilizing groups that are generally attached to one or both termini of antisense compounds to enhance properties such as, for example, nuclease stability. Included in stabilizing groups are cap structures. These terminal modifications protect the antisense compound having terminal nucleic acid from exonuclease degradation, and can help in delivery and/or localization within a cell. The cap can be present at the 5′-terminus (5′-cap), or at the 3′-terminus (3′-cap), or can be present on both termini. Cap structures are well known in the art and include, for example, inverted deoxy abasic caps. Further 3′ and 5′-stabilizing groups that can be used to cap one or both ends of an antisense compound to impart nuclease stability include those disclosed in WO 03/004602 published on Jan. 16, 2003.

Cell Culture and Antisense Compounds Treatment

The effects of antisense compounds on the level, activity or expression of SOD-1 nucleic acids can be tested in vitro in a variety of cell types. Cell types used for such analyses are available from commerical vendors (e.g. American Type Culture Collection, Manassas, Va.; Zen-Bio, Inc., Research Triangle Park, NC; Clonetics Corporation, Walkersville, Md.) and are cultured according to the vendor's instructions using commercially available reagents (e.g. Invitrogen Life Technologies, Carlsbad, Calif.). Illustrative cell types include, but are not limited to, HepG2 cells, Hep3B cells, primary hepatocytes, A431 cells, and SH-SY5Y cells.

In Vitro Testing of Oligonucleotides

Described herein are methods for treatment of cells with oligonucleotides, which can be modified appropriately for treatment with other antisense compounds.

Cells may be treated with oligonucleotides when the cells reach approximately 60-80% confluency in culture.

One reagent commonly used to introduce oligonucleotides into cultured cells includes the cationic lipid transfection reagent LIPOFECTIN (Invitrogen, Carlsbad, Calif.). Oligonucleotides may be mixed with LIPOFECTIN in OPTI-MEM 1 (Invitrogen, Carlsbad, Calif.) to achieve the desired final concentration of oligonucleotide and a LIPOFECTIN concentration that may range from 2 to 12 ug/mL per 100 nM oligonucleotide.

Another reagent used to introduce oligonucleotides into cultured cells includes LIPOFECTAMINE (Invitrogen, Carlsbad, Calif.). Oligonucleotide is mixed with LIPOFECTAMINE in OPTI-MEM 1 reduced serum medium (Invitrogen, Carlsbad, Calif.) to achieve the desired concentration of oligonucleotide and a LIPOFECTAMINE concentration that may range from 2 to 12 ug/mL per 100 nM oligonucleotide.

Another technique used to introduce oligonucleotides into cultured cells includes electroporation.

Cells are treated with oligonucleotides by routine methods. Cells may be harvested 16-24 hours after oligonucleotide treatment, at which time RNA or protein levels of target nucleic acids are measured by methods known in the art and described herein. In general, when treatments are performed in multiple replicates, the data are presented as the average of the replicate treatments.

The concentration of oligonucleotide used varies from cell line to cell line. Methods to determine the optimal oligonucleotide concentration for a particular cell line are well known in the art. Oligonucleotides are typically used at concentrations ranging from 1 nM to 300 nM when transfected with LIPOFECTAMINE. Oligonucleotides are used at higher concentrations ranging from 625 to 20,000 nM when transfected using electroporation.

RNA Isolation

RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods of RNA isolation are well known in the art. RNA is prepared using methods well known in the art, for example, using the TRIZOL Reagent (Invitrogen, Carlsbad, Calif.) according to the manufacturer's recommended protocols.

Analysis of Inhibition of Target Levels or Expression

Inhibition of levels or expression of a SOD-1 nucleic acid can be assayed in a variety of ways known in the art. For example, target nucleic acid levels can be quantitated by, e.g., Northern blot analysis, competitive polymerase chain reaction (PCR), or quantitative real-time PCR. RNA analysis can be performed on total cellular RNA or poly(A)+ mRNA. Methods of RNA isolation are well known in the art. Northern blot analysis is also routine in the art. Quantitative real-time PCR can be conveniently accomplished using the commercially available ABI PRISM 7600, 7700, or 7900 Sequence Detection System, available from PE-Applied Biosystems, Foster City, Calif. and used according to manufacturer's instructions.

Quantitative Real-Time PCR Analysis of Target RNA Levels

Quantitation of target RNA levels may be accomplished by quantitative real-time PCR using the ABI PRISM 7600, 7700, or 7900 Sequence Detection System (PE-Applied Biosystems, Foster City, Calif.) according to manufacturer's instructions. Methods of quantitative real-time PCR are well known in the art.

Prior to real-time PCR, the isolated RNA is subjected to a reverse transcriptase (RT) reaction, which produces complementary DNA (cDNA) that is then used as the substrate for the real-time PCR amplification. The RT and real-time PCR reactions are performed sequentially in the same sample well. RT and real-time PCR reagents may be obtained from Invitrogen (Carlsbad, Calif.). RT real-time-PCR reactions are carried out by methods well known to those skilled in the art.

Gene (or RNA) target quantities obtained by real time PCR are normalized using either the expression level of a gene whose expression is constant, such as cyclophilin A, or by quantifying total RNA using RIBOGREEN (Invitrogen, Inc. Carlsbad, Calif.). Cyclophilin A expression is quantified by real time PCR, by being run simultaneously with the target, multiplexing, or separately. Total RNA is quantified using RIBOGREEN RNA quantification reagent (Invitrogen, Inc. Eugene, Oreg.). Methods of RNA quantification by RIBOGREEN are SOD-1 ght in Jones, L. J., et al, (Analytical Biochemistry, 1998, 265, 368-374). A CYTOFLUOR 4000 instrument (PE Applied Biosystems) is used to measure RIBOGREEN fluorescence.

Probes and primers are designed to hybridize to a SOD-1 nucleic acid. Methods for designing real-time PCR probes and primers are well known in the art, and may include the use of software such as PRIMER EXPRESS Software (Applied Biosystems, Foster City, Calif.).

Analysis of Protein Levels

Antisense inhibition of SOD-1 nucleic acids can be assessed by measuring SOD-1 protein levels. Protein levels of SOD-1 can be evaluated or quantitated in a variety of ways well known in the art, such as immunoprecipitation, Western blot analysis (immunoblotting), enzyme-linked immunosorbent assay (ELISA), quantitative protein assays, protein activity assays (for example, caspase activity assays), immunohistochemistry, immunocytochemistry or fluorescence-activated cell sorting (FACS). Antibodies directed to a target can be identified and obtained from a variety of sources, such as the MSRS catalog of antibodies (Aerie Corporation, Birmingham, Mich.), or can be prepared via conventional monoclonal or polyclonal antibody generation methods well known in the art. In certain embodiments, the compounds herein provide improved reduction in protein levels.

In Vivo Testing of Antisense Compounds

Antisense compounds, for example, modified oligonucleotides, are tested in animals to assess their ability to inhibit expression of SOD-1 and produce phenotypic changes, such as, improved motor function. In certain embodiments, motor function is measured by walking initiation analysis, rotarod, grip strength, pole climb, open field performance, balance beam, hindpaw footprint testing in the animal. Testing may be performed in normal animals, or in experimental disease models. For administration to animals, oligonucleotides are formulated in a pharmaceutically acceptable diluent, such as phosphate-buffered saline. Administration includes parenteral routes of administration, such as intraperitoneal, intravenous, and subcutaneous. Oligonucleotide dosage and dosing frequency depends upon multiple factors such as, but not limited to, route of administration and animal body weight. Following a period of treatment with oligonucleotides, RNA is isolated from CNS tissue or CSF and changes in SOD-1 nucleic acid expression are measured.

ISIS 333611, previously disclosed in WO 2005/040180, was also designated as a benchmark or comparator oligonucleotide. ISIS 333611 was recently tested in human clinical trials. See, MILLER et al., “An antisense oligonucleotide against SOD1 delivered intrathecally for patients with SOD1 familial amyotrophic lateral sclerosis: a phase 1, randomised, first-in-man study” Lancet Neurol. (2013) 12(5): 435-442.

The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 7,000 nM modified oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR.

Human primer probe set RTS3898 (forward sequence CTCTCAGGAGACCATTGCATCA, designated herein as SEQ ID NO: 11; reverse sequence TCCTGTCTTTGTACTTTCTTCATTTCC; designated herein as SEQ ID NO: 12; probe sequence CCGCACACTGGTGGTCCATGAAAA, designated herein as SEQ ID NO: 13) was used to measure mRNA levels. In cases where the oligonucleotide overlapped the amplicon of the primer probe set, an alternative primer probe set, HTS90 (forward sequence CGTGGCCTAGCGAGTTATGG, designated herein as SEQ ID NO: 14; reverse sequence GAAATTGATGATGCCCTGCA; designated herein as SEQ ID NO: 15; probe sequence ACGAAGGCCGTGTGCGTGCTGX, designated herein as SEQ ID NO: 16), was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells. ‘n.d.’ indicates that inhibition levels were not measured using the particular primer probe set.

The newly designed modified oligonucleotides in the Tables below were designed as 5-10-5 MOE gapmers. The 5-10-5 MOE gapmers are 20 nucleosides in length, wherein the central gap segment is comprised of ten 2′-deoxyribonucleosides and is flanked by wing segments on the 5′ direction and the 3′ directions comprising five nucleosides each. Each nucleoside in the 5′ wing segment and each nucleoside in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. “Start site” indicates the 5′-most nucleoside to which the gapmer is targeted in the human gene sequence. “Stop site” indicates the 3′-most nucleoside to which the gapmer is targeted human gene sequence. Each gapmer listed in the Tables below is targeted to either the human SOD-1 mRNA, designated herein as SEQ ID NO: 1 (GENBANK Accession No. NM_000454.4) or the human SOD-1 genomic sequence, designated herein as SEQ ID NO: 2 (GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000). ‘n/a.’ indicates that the modified oligonucleotide does not target that particular gene sequence with 100% complementarity.

Example 2 Inhibition of Human SOD-1 in HepG2 Cells by MOE Gapmers

Modified oligonucleotides were designed targeting a superoxide dismutase 1, soluble (SOD-1) nucleic acid and were tested for their effects on SOD-1 mRNA in vitro. ISIS 146143, ISIS 150438-150440, ISIS 150442, ISIS 150450, ISIS 150455-150457, ISIS 150459, ISIS 150461, ISIS 150469, ISIS 150473, ISIS 150478, ISIS 150484, ISIS 150486, ISIS 150494, ISIS 150508-150510, ISIS 333607, ISIS 333608, ISIS 333611, ISIS 333618, previously disclosed in WO 2005/040180, were also included in this assay. The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 5,000 nM modified oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR.

Human primer probe set RTS3898 was used to measure mRNA levels. In cases where the oligonucleotide overlapped the amplicon of the primer probe set, an alternative primer probe set, HTS90, was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells. ‘n.d.’ indicates that inhibition levels were not measured using the particular primer probe set.

The newly designed modified oligonucleotides in the Tables below were designed as 5-10-5 MOE gapmers. The 5-10-5 MOE gapmers are 20 nucleosides in length, wherein the central gap segment is comprised of ten 2′-deoxyribonucleosides and is flanked by wing segments on the 5′ direction and the 3′ directions comprising five nucleosides each. Each nucleoside in the 5′ wing segment and each nucleoside in the 3′ wing segment has a 2′-MOE modification. The internucleoside linkages throughout each gapmer are phosphorothioate linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. “Start site” indicates the 5′-most nucleoside to which the gapmer is targeted in the human gene sequence. “Stop site” indicates the 3′-most nucleoside to which the gapmer is targeted human gene sequence. Each gapmer listed in the Tables below is targeted to either the human SOD-1 mRNA, designated herein as SEQ ID NO: 1 (GENBANK Accession No. NM_000454.4) or the human SOD-1 genomic sequence, designated herein as SEQ ID NO: 2 (GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000). ‘n/a’ indicates that the modified oligonucleotide does not target that particular gene sequence with 100% complementarity.

Example 3 Inhibition of Human SOD-1 in HepG2 Cells by Deoxy, MOE and cEt Gapmers

Modified oligonucleotides were designed targeting a superoxide dismutase 1, soluble (SOD-1) nucleic acid and were tested for their effects on SOD-1 mRNA in vitro. ISIS 333611, which was previously described in WO 2005/040180, was included as a benchmark. ISIS 590067, ISIS 590074, ISIS 590082, ISIS 590130, ISIS 590138, and ISIS 590146, which are 5-10-5 MOE gapmers as described above in Example 1, were also included in this assay. ISIS 590512, which has a similar sequence as ISIS 333611 but with deoxy, MOE, and cEt sugar modifications, was also included in this study.

The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 3,000 nM modified oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR.

Human primer probe set RTS3898 was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells. ‘n.d.’ indicates that inhibition levels were not measured.

The newly designed modified oligonucleotides in the Tables below were designed as deoxy, MOE, and cEt gapmers. The gapmers are 17 nucleosides in length wherein each nucleoside has a MOE sugar modification, a cEt sugar modification, or a deoxy moiety. The sugar chemistry of each oligonucleotide is denoted as in the Chemistry column, where ‘k’ indicates a cEt modified sugar; ‘d’ indicates a 2′-deoxyribose; and ‘e’ indicates a 2′-MOE modified sugar. The internucleoside linkages throughout each gapmer are phosphorothioate linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. “Start site” indicates the 5′-most nucleoside to which the gapmer is targeted in the human gene sequence. “Stop site” indicates the 3′-most nucleoside to which the gapmer is targeted human gene sequence. Each gapmer listed in the Tables below is targeted to either the human SOD-1 mRNA, designated herein as SEQ ID NO: 1 (GENBANK Accession No. NM_000454.4) or the human SOD-1 genomic sequence, designated herein as SEQ ID NO: 2 (GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000). ‘n/a’ indicates that the modified oligonucleotide does not target that particular gene sequence with 100% complementarity.

Example 4 Inhibition of Human SOD-1 in HepG2 Cells by Deoxy, MOE and cEt Gapmers

Modified oligonucleotides were designed targeting a superoxide dismutase 1, soluble (SOD-1) nucleic acid and were tested for their effects on SOD-1 mRNA in vitro. ISIS 333611, a 5-10-5 MOE gapmer which was previously described in WO 2005/040180, was included as a benchmark.

The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 4,000 nM modified oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR.

Human primer probe set RTS3898 was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells. ‘n.d.’ indicates that inhibition levels were not measured.

The newly designed modified oligonucleotides in the Tables below were designed as deoxy, MOE, and cEt gapmers or 5-10-5 gapmers. The 5-10-5 MOE gapmers are 20 nucleosides in length, wherein the central gap segment is comprised of ten 2′-deoxyribonucleosides and is flanked by wing segments on the 5′ direction and the 3′ direction comprising five nucleosides each. Each nucleoside in the 5′ wing segment and each nucleoside in the 3′ wing segment has a 2′-MOE modification. The deoxy, MOE and cEt oligonucleotides are 17 nucleosides in length wherein the nucleoside has a MOE sugar modification, a cEt sugar modification, or a deoxy moiety. The sugar chemistry of each oligonucleotide is denoted as in the Chemistry column, where ‘k’ indicates a cEt modified sugar; ‘d’ indicates a 2′-deoxyribose; and ‘e’ indicates a 2′-MOE modified sugar. The internucleoside linkages throughout each gapmer are phosphorothioate linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. “Start site” indicates the 5′-most nucleoside to which the gapmer is targeted in the human gene sequence. Each gapmer listed in the Tables below is targeted to either the human SOD-1 mRNA, designated herein as SEQ ID NO: 1 (GENBANK Accession No. NM_000454.4) or the human SOD-1 genomic sequence, designated herein as SEQ ID NO: 2 (GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000). ‘n/a.’ indicates that the modified oligonucleotide does not target that particular gene sequence with 100% complementarity.

Example 5 Inhibition of Human SOD-1 in HepG2 Cells by Deoxy, MOE and cEt Gapmers

Modified oligonucleotides were designed targeting an SOD-1 nucleic acid and were tested for their effects on SOD-1 mRNA in vitro. ISIS 333611, a 5-10-5 MOE gapmer, which was previously described in WO 2005/040180, was included as a benchmark.

The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 5,000 nM modified oligonucleotide. After a treatment period of approximately 24 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR.

Human primer probe set RTS3898 was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells. ‘n.d.’ indicates that inhibition levels were not measured.

The newly designed modified oligonucleotides in the Tables below were designed as deoxy, MOE, and cEt gapmers. The gapmers are 17 nucleosides in length wherein each nucleoside has a MOE sugar modification, a cEt sugar modification, or a deoxy moiety. The sugar chemistry of each oligonucleotide is denoted as in the Chemistry column, where ‘k’ indicates a cEt modified sugar; ‘d’ indicates a 2′-deoxyribose; and ‘e’ indicates a 2′-MOE modified sugar. The internucleoside linkages throughout each gapmer are phosphorothioate linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. “Start site” indicates the 5′-most nucleoside to which the gapmer is targeted in the human gene sequence. Each gapmer listed in the Tables below is targeted to either the human SOD-1 mRNA, designated herein as SEQ ID NO: 1 (GENBANK Accession No. NM_000454.4) or the human SOD-1 genomic sequence, designated herein as SEQ ID NO: 2 (GENBANK Accession No. NT_011512.10 truncated from nucleotides 18693000 to 18704000). ‘n/a.’ indicates that the modified oligonucleotide does not target that particular gene sequence with 100% complementarity.

Example 6 Dose-Dependent Inhibition of Human SOD-1 with Modified Oligonucleotides in HepG2 Cells

Gapmers from the studies described above exhibiting significant in vitro inhibition of SOD-1 mRNA were selected and tested at various doses in HepG2 cells. Benchmark compound ISIS 333611 and other compounds previously disclosed in WO 2005/040180, including ISIS 146144, 146145, 150445, 150446, 150447, 150454, 150463, 150465, 333606, 333609, and 333611 were also tested.

The modified oligonucleotides were tested in a series of experiments that had similar culture conditions. The results for each experiment are presented in separate tables shown below. Cells were plated at a density of 20,000 cells per well and transfected using electroporation with 0.813 μM, 1.625 μM, 3.250 μM, 6.500 μM, and 13.000 μM concentrations of modified oligonucleotide, as specified in the Tables below. After a treatment period of approximately 16 hours, RNA was isolated from the cells and SOD-1 mRNA levels were measured by quantitative real-time PCR. Human primer probe set RTS3898 was used to measure mRNA levels. SOD-1 mRNA levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent inhibition of SOD-1, relative to untreated control cells.

The half maximal inhibitory concentration (IC₅₀) of each oligonucleotide is also presented. SOD-1 mRNA levels were significantly reduced in a dose-dependent manner in modified oligonucleotide treated cells.

Example 14 Tolerability of SOD-1 Modified Oligonucleotides in a Rat Model

Gapmers from the studies described above, including benchmark compound ISIS 333611, which was previously disclosed in WO 2005/040180, were tested for tolerability in Sprague-Dawley rats.

The modified oligonucleotides were tested in a series of experiments that had similar conditions. Rats were injected intrathecally with 3 mg of a single dose of ISIS oligonucleotide. A control group of rats was injected intrathecally with PBS. Acute tolerability was assessed 3 hours post-dose using a functional observational battery (FOB). This score is used to evaluate the acute tolerability of a compound with lower scores denoting better tolerated compounds. Control animals usually have a score of ‘0’ or ‘1’. At 3 hours post injection, the rats are observed by placing each rat on the cage top and evaluating certain functions, assigning a number of ‘0’ or ‘1’ depending on whether the rat exhibits normal function in the region of interest (0) or does not (1) for each function, and then adding the total scores. Seven regions are assessed, including tail, hind paws, hind legs, hind end, front posture, fore paws, and head. The results of the scoring are presented in the Table below. As presented in the Table, several newly designed oligonucleotides demonstrated more acute tolerability compared to the benchmark, ISIS 333611.

Tolerability was also assessed 8 weeks post-dose by measuring the levels of IBA1, a microglial marker, and GFAP, an astrocytic marker, in the lumbar spinal cord region. Both IBA1 and GFAP are markers of CNS inflammation (Frank, M G, Brain Behav. Immun. 2007, 21, 47-59), hence the higher the level of either marker, the less tolerable the antisense oligonucleotide is deemed to be in this rat model.

IBA1 mRNA levels were measured with primer probe set rAIF1_LTS00219 (forward sequence AGGAGAAAAACAAAGAACACCAGAA, designated herein as SEQ ID NO: 5; reverse sequence CAATTAGGGCAACTCAGAAATAGCT, designated herein as SEQ ID NO: 6; probe sequence CCAACTGGTCCCCCAGCCAAGA, designated herein as SEQ ID NO: 7).

Example 15 Dose Dependent Inhibition of Human SOD-1 in a Transgenic Rat Model

Gapmers from the studies described above, including benchmark compound ISIS 333611, were tested in an SOD-1 transgenic rat model (Taconic, Cat#2148-F and 2148-M). These hemizygous rats express mutant human SOD-1 in the spinal cord, many brain regions, and peripheral organs.

Rats were injected intrathecally with 10, 30, 100, 300, 1000, or 3000 μg of a gapmer listed in the table below or with only PBS. Two weeks later, the animals were sacrificed. Inhibition of SOD-1 mRNA in the lumbar spinal cord, cervical spinal cord, rostral cortex, and caudal cortex was assessed by RT-PCR using primer probe set RTS3898, described in Example 1. The data is presented below as ED₅₀ values, and indicates that the oligonucleotides inhibited SOD1 mRNA in multiple CNS tissues more potently than Isis 333611. Indeed, ED₅₀ values for Isis No. 333611 could not even be calculated, as indicated by an entry of “n/a,” because even the highest concentration tested (3000 μg) did not inhibit SOD-1 mRNA greater than 55-65%. “n.d.” indicates that there is no data available for the indicated sample.

Example 16 Tolerability of SOD-1 Modified Oligonucleotides in Rats

Gapmers from the studies described above, including benchmark compound ISIS 333611, were tested for tolerability in Sprague-Dawley rats. Groups of 4 to 6 rats were injected intrathecally with 1 mg or 3 mg of a single dose of an ISIS oligonucleotide. A control group of rats was injected intrathecally with PBS. Acute tolerability was assessed 3 hours post-dose, as described in Example 14. The results for the 1 mg dose are the averages for each group following one experiment. The results for the 3 mg dose are the averages for each group across two replicate experiments. The results of the study, presented in the table below, indicate that several newly designed oligonucleotides were more tolerable than the benchmark, ISIS 333611.

Example 17 Dose Dependent Inhibition of Human SOD-1 in a Transgenic Mouse Model

In order to confirm the results obtained in transgenic rats in another species, gapmers from the studies described above were tested in an SOD-1 transgenic mouse model that expresses the same G93A human mutant SOD1 gene that the transgenic rat expresses (see Examples 12 and 15).

Mice received an intracerebral ventricular bolus (ICVB) of 10, 30, 100, 300, or 700 μg of a gapmer listed in the table below, or PBS. Two weeks later, the animals were sacrificed. Inhibition of SOD-1 mRNA in the lumbar spinal cord and cortex was assessed by RT-PCR using primer probe set RTS3898, described in Example 1. The data is presented below as ED₅₀ values, and indicates that the oligonucleotides inhibited SOD1 mRNA more potently than Isis 333611 in both rats and mice.

Example 18 Tolerability of SOD-1 Modified Oligonucleotides in Mice

Gapmers from the studies described above, including benchmark compound ISIS 333611, were tested for tolerability in C57bl6 mice. Mice were injected stereotaxically into the cerebral ventricles with 700 ug of a single dose of ISIS oligonucleotide. A control group of mice was injected into the cerebral ventricle with PBS. Acute tolerability was assessed at 3 hours post injection using a functional observation battery (FOB) different from that used for the rats. Each mouse was evaluated according to 7 different criteria. The 7 criteria are (1) the mouse was bright, alert, and responsive; (2) the mouse was standing or hunched without stimuli; (3) the mouse shows any movement without stimuli (4) the mouse demonstrates forward movement after its lifted; (5) the mouse demonstrates any movement after its lifted; (6) the mouse responds to a tail pinch; (7) regular breathing. For each of the 7 different criteria, each mouse was given a sub-score of 0 if it met the criteria or 1 if it did not. After all of the 7 criteria were evaluated, the sub-scores were summed for each mouse and then averaged for each group. For example, if a mouse was bright, alert, and responsive 3 hours after the 700 μg ICV dose, and met all other criteria, it would get a summed score of 0. If another mouse was not bright, alert, and responsive 3 hours after the 700 μg ICV dose but met all other criteria, it would receive a score of 1. Saline treated mice generally receive a score of 0. A score at the top end of the range would be suggestive of acute toxicity.

Body weights were measured throughout the study and are reported below as percent change at 8 weeks relative to baseline. Long term tolerability was assessed 8 weeks post-dose by measuring the levels of IBA1 and GFAP, as described in Example 14. IBA1 and GFAP mRNA levels are reported relative to PBS treated animals. The results of the study, presented in the tables below, indicate that several newly designed oligonucleotides were more tolerable, in rats and mice, compared to the benchmark, ISIS 333611.

Example 19 Dose Dependent Inhibition of Monkey SOD-1 in Cynomolgus Monkey

Isis No. 666853 was tested in cynomolgus monkey. There is one mismatch between Isis No. 666853 and cynomolgus monkey SOD-1, and there are 17 contiguous bases in Isis No. 666853 that are 100% complementary to cynomolgus monkey SOD-1.

Groups of 6-10 male and female monkeys received an intrathecal lumbar bolus of PBS or 4, 12, or 35 mg of Isis No. 666853 on days 1, 14, 28, 56, and 84 of the study. Each group received the same dose on all five dosing days. On day 91, the animals were sacrificed. Inhibition of SOD-1 mRNA in the lumbar, thoracic, and cervical spinal cord and frontal cortex, motor cortex, hippocampus, pons, and cerebellum was assessed by RT-PCR using primer probe set RTS3898. The data is presented below as the average percent inhibition for each treatment group, relative to the PBS treated group. The results indicate that Isis No. 666853 inhibited SOD-1 mRNA in multiple target tissues in cynomolgus monkey.

Treatment with 666853 was well tolerated for the duration of the 13 week study and there were no clinical observations of adverse reactions in monkeys.
